NEWELL SANDERS, OF CHATTANOOGA, TENNESSEE, ASSIGNOR TO THE OHATTANOOGA PLOW COMPANY, OF SAME PLACE.

PLOW.

SPECIFICATION forming part of Letters Patent No. 662,974, dated, December 4, 1900. Application filed January 20, 1900- Serial No. 2,201. (No model.)

To aZZ whom, it may concern.-

Be it known that I, NEWELL SANDERS, a citizen of the United States, residing at Ghattanooga, Tennessee, have invented certain new and useful Improvements in Plows, of which the following is a specification.

My invention is an improvement in wheelplows, and I have shown it in connection with a disk form of plow, the features of novelty relating particularly to an arrangement of clevis and wheel with intermediate connections whereby upon the turning of the clevis the direction of the wheel will be altered in turning the plow.

In the accompanying drawings, Figure 1 shows a plan view of my invention combined with the plow. Fig. 2 is a bottom plan view of part of the beam with the clevis pivoted thereto. Fig. 3 is an edge view of the clevis and doubletree-strap.

In the drawings the main beam is shown at 1, the plow-dish at 2, the land-Wheel at 3, and the furrow-wheel at 4. This furrowwheel is supported on a spindle 5, which is journaled in any suitable bearing at 6 which will allow the upright part of the spindle to turn in said bearing, and thus change the direction of the furrow-wheel. The bearing 6 is supported upon the arm or. rod 7, which is adjustably supported in the front end of the main beam. To the spindle of the furrowwheel an arm 8 is secured, and it is through this arm, which is connected by a rod 9 with the clevis 10, that the spindle of the furrow- Wheel is turned. The clevis 10 is pivoted to the front part of beam 11, which is rigidly secured to the main beam by bolts 12. The clevis Works upon the broad upper surface of the front part of the beam, and it is pivoted to said beam at 13, this pivot being at the rear end of the clevis and as near as practicable to the left-hand edge of the front part of beam and in line from front to rear with the left-hand hole 14 of a series of holes intended to receive the doubletree connection at the front end of the clevis.

To the left of the hole 14 a hole 15 is made in the clevis, and this passes through a projection 16 on the lower side of the clevis. This hole receives the rod 9, which connects with the arm 8 for turning the furrow-wheel spindle, said rod extending under the fixed beam with its clevis.

By reason of the left-hand position of the hole 15 there will be little or no tendency of the wheel to pull the clevis around while the plow is being drawn straight forward. While turning at the corner of the land, however, the side pull of the horses easily turns the clevis on its pivot, and this through the arm 8 and rod 9 turns the furrow-wheel. The series of holes in the clevis permits the neces sary variation of the hitch in changing from two to three horses or for different Widths of furrow.

A guide 18 is arranged on the under side of the clevis engaging the front edge of the front part of beam, which is on a curve struck from the pivot of the clevis.

The doubletree-strap 19 is pivoted by the same bolt which pivots the clevis to the front part of beam.

When it is not desired to operate the clevis, as shown, the clevis may be fixed to the front part of beam by a bolt inserted in an opening 20 and a second opening 21 in the beam. These openings register when the clevis is in the position shown in Fig. 1 relative to the beam.

The broad surface of the top of the clevis without obstruction of any kind answers as a platform on which the doubletree works.

By the arrangement of the series of boltholes relative to the pivot of the clevis the tendency of the forward draft will be to hold the clevis to the left or to keep it straight forward no matter in which hole the doubletree-bolt is located, and the clevis will thus be kept drawn against the stop 22 on the right-hand side. In this position of the clevis it will be seen that the adjustable furrowwheel is directed straight forward. The stop consists of ashoulder 23 on the forward part of the fixed beam and a lug 22 on the clevis.

The stop might be on the left side by putting 9 the lug on the beam instead of clevis, but preferably it is on the right-hand side, as shown.

The above description applies to a clevis and turning arrangement for right-hand oted thereto free to turn whenside draft takes place, an adj ustable wheel and a conn'ecclevis free to turn when side draft takesplace, a pivot-ally-supported wheel and a connection between the clevis and wheel for positively adjusting the wheel as the clevis is turned, substantially as described.

3. In combination, a plow-beam, a pivoted clevis free to turn when side draft takes place, a wheel having its spindle journaled so as to turn, an arm connected with the spindle and a rod connecting the clevis and arm to positively operate the arm as the clevis is turned, substantially as described.

4. In combination, a plow-beam, a clevis pivoted thereto, a stop for the clevis, a means of connection for the doubletree adapted to keep the clevis limited by its stop to normal position during forward draft or side draft in one direction, and a connection between the clevis and an adjustable wheel adapted to move the wheel when side draft takes place in the other direction, substantially as described.

5. In combination, the beam, a pivoted clevis, a stop for limiting the movement of the clevis in one direction, a series of holes for the variable hitch, said holes being arranged relatively to the pivot of the clevis and the stop to cause the draft to hold the clevis in normal position against the stop, and an adjustable Wheel with a connection between the same and the clevis, substantially as described.

6. In combination, the beam having a .curved edge, a clevis pivoted to the beam and having a guide engaging the curved edge, an adjustable Wheel and a connection between the same and the clevis, substantially as described.

7. In combination, a plow-beam, a clevis pivoted near one edge of the same and having a series of holes near its front edge extending from one edge of the beam toward the other, a stop for the clevis, an adjustable wheel and a connection between the wheel and clevis, substantially as described.

8. In combination, the beam, a clevis pivoted to and resting upon the beam and having a broad surface upon which the doubletree may rest, and a doubletree-strap, substantially as described.

9. In combination, the beam, a clevis pivoted thereto and free to turn under side draft, an adjustable wheel, a connection between said wheel and the clevis to positively turn the Wheel as the clevis is turned, and means by which the clevis may be fixed to the beam, substantially as described.

10. In combination, the beam, a'clevis comprising a flat plate pivoted thereto and resting upon the beam, and a strap held by the pivot-bolt of the clevis and adjustable on said clevis, substantially as described.

In testimony whereof I affiX my signature in presence of two witnesses.

NEWELL SANDERS.
